igus presents new cable drums without slip ring

igus GmbH recently presented the new “E-Spool”, the first retractable energy chain system. The experience gained in customer applications since the launch have led to further expansion of the range.

Room for a wide range of different cable fillings

Compact and durable, the system combines the advantages of two different energy chains: a standard “E-Chain” from the E2/000 series is routed via a spool and – thanks to the integrated return spring – always ensures the exactly correct length and tension of the energy chain. Customers have a choice of three different length versions (0-4 m, 4-7 m and 7-14 m). In its initial position, the chain is completely and compactly wound up. Depending on the number of cables to be guided, the “E-Chain” from the 1400 series with inner widths 80 and 125 mm can be ordered. The “Twisterband” connects the spool with the shaft bracket, which serves as the interface to the permanently installed cables. In “classic” cable drums this task is usually taken over by sliding contacts. The “E-Spool” concept is far more flexible here, because in contrast to sliding contacts, cables for data, compressed air and fluids can be connected in a single system without interruption, and be replaced or modified at any time. The “Twisterband” TB 30 provides sufficient space for cable diameters of up to 16 mm. Where a large number of cables are involved, the “Twisterband” can also route these to both sides of the chain drum.

These concrete advantages make the “E-Spool” a complete modular replacement for classic cable drums. In addition, the “E-Spool” can be just the solution where space is tight: additional space for storing the chain, as is the case with freely suspended or zigzag applications, is no longer required. The “E-Spool” is used in lifting platforms, sorting lines, mobile cranes, platform applications or assembly or process cranes with grippers.

Application example: mobile ventilation system

The German company Becker Elektro Stapler Service was one of the first customers to purchase the new “E-Spool”. They use energy chains in a telescopic ventilation system. Such systems prevent fruit blossoms being destroyed by frost, thus ruining the harvest. The system features a special propeller which makes sure air circulates above the fruit plantation, preventing frost settling on the fruit trees. It is mobile and can be extended vertially up to 10 metres , allowing an area of around 2 hectares to be covered. The “E-Spool” supplies the system motor with media and energy cables.

The “E-Spool” from igus is available in three different lengths (0.4 m, 4-7 m and 7-14 m) as well as with the inner widths 80 and 125 mm (E-Chain of the 1400 series).
